Portas utilizadas pelo Sistema Operacional

A lista a seguir exibe algumas portas que são utilizadas para prover alguns serviços do Sistema Operacional. Algumas destas portas são utilizadas por outros aplicativos, sendo que alguns deles estão presentes nesta lista.

No entanto, nada impede que algum aplicativo utilize uma porta que já está reservada para o Sistema Operacional ou qualquer outro aplicativo. O detalhe é que se isto acontecer, não há uma maneira de garantir o adequado funcionamento dos aplicativos que estão utilizando a mesma porta.

Desta forma, é muito importante que seja configurada sempre alguma porta que não esteja sendo utilizada no momento, seja pelo Sistema Operacional, seja por qualquer outro aplicativo. A melhor opção é sempre utilizar valores iguais ou acima a 1024, pois os valores inferiores a 1024 têm uma maior chance de estarem sendo utilizados pelo Sistema Operacional ou por drivers que porventura estejam instalados.
